I replaced my water pump as well and when doing that someone had recommended this as well I put this on with the water pump and a new thermostat and have noticed a much better temperature reading and would recommend doing this as well if I had to do it all over again I would go the same route

Put this on a 1996 XJ along with a flowkooler high flow water pump, and it fixed the occasional overheating issue I had. Be sure to use gasket sealer on this! There is a pretty small sealing surface on one side, and I didn't trust the cork gasket to seal it.

Waste of $90 and two hours. This pump didn't make any measurable difference in the cooling of my Jeep. Let me be clear: there is nothing wrong with my cooling system. My Cherokee just gets too hot too easy. It will hit 200 degrees and stay there controlled by the thermostat. But give it a hill around town (not a crazy hill, either) and the temp climbs right up to the point that the EL fan kicks in. I bought the hype and tried this pump. It made absolutely NO difference. Should have spent my money on an Ohooogah horn.
